As I just mentioned in another thread, I just got the AK Nitro set up. I cannot say anything about Arozzi and admittedly I have only had one night in the AK chair, but it is the first time I have spent that much on a chair and after just one evening I have no regrets and wish I bought it sooner. The chair was comfortable while keeping me sat correctly - that in itself is a miracle, as a result, instead of the usual aches I get in my upper body after gaming (thanks to slouching) I actually finished feeling good - something I haven't felt for a good few months now due to the constant strain I put on my back
